There is no 0th character, so it's an error. If they had wanted to
avoid an error, they'd have had to return None or some other flag, and
that's not pythonic.

A slice is more tolerant, by definition. It gives you all the items in
the range you specify, and the resulting string (in this case) is equal
to the original one.
